可控硅是硅半导体元件,它在作用上很像一只闸流管或水银整流器,但它具有体积小,重量轻,开关时间短,功率增益大,效率高,寿命长和使用维护方便等特点,所以在矿山企业中已越来越广泛地得到应用。特别是在可控整流,直流—交流逆变,交流变频,电机无级调速,电机励磁,自动功率控制和无触点交直流开关等方面的使用,使可控硅技术跨入了强电领域,对于减轻重量,提高质 Silicon is a silicon semiconductor device, which acts like a thyristor or mercury rectifier, but it has small size, light weight, short switching time, large power gain, high efficiency, long life and ease of use and maintenance Characteristics, it has been more and more widely used in mining enterprises. Especially in the controllable rectifier, DC - AC inverter, AC inverter, stepless speed regulation of the motor, the motor excitation, automatic power control and non-contact AC and DC switches and other aspects of the use of SCR technology into the strong Field, to reduce weight, improve quality
